The information in this article applies to:
- Microsoft C/C++ Compiler (CL.EXE), included with:
- Microsoft C/C++ for MS-DOS, version 7.0
- Microsoft Visual C++, versions 1.0, 1.5, 1.51, 1.52

SYMPTOMS
========
The sample code fragment listed at the end of this article incorrectly deletes a
typedef of a pointer to a structure, which generates the following compiler
errors:
- For Visual C++ 4.2 for Windows NT:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'toil.c', line
4094)
- For Visual C++ 4.1 for Windows NT:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'toil.c', line
4051)
- For Visual C++ 4.0 for Windows NT:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'toil.c', line
3128)
- For Visual C++ 2.x for Windows NT:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'toil.c', line
2847)
- For Visual C++ 1.0 for Windows NT:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file '@(#)main.c:1.82',
line 289)
- For Visual C++ version 1.5x for Windows:
fatal error C1059: compiler is out of near heap space
- For Visual C++ version 1.0 for Windows:
fatal error C1063
- For C/C++ version 7.0:
fatal error C1001: INTERNAL COMPILER ERROR (compiler file '2pass/getattr.c',
line 346) Contact Microsoft Product Support Services
RESOLUTION
==========
The above error messages are misleading and do not point out the real problem,
which is that you cannot delete a typedef. Additionally, the operand of delete
must be a pointer returned by the new operator. Using delete on a pointer to an
object not allocated with new gives unpredictable results.
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

Sample Code to Reproduce Problem
--------------------------------
/* Compile options needed: none
*/
typedef struct {
int x;
}MY_STRUCT, *LPMY_STRUCT;
LPMY_STRUCT pMyStruct = new MY_STRUCT;
void MyTestFunction()
{
delete pMyStruct; // ok.
delete LPMY_STRUCT; // Can not delete a type.
}
